Installation must conform to applicable code and all requirements listed in the installation manual.
•
Each temperature and pressure relief valve (T&P valve) must have a properly-sized discharge pipe installed. See code/installation manual. Each discharge pipe must terminate a maximum of six inches above a floor drain or external to the building.
•
Do not cap or plug the T&P discharge pipes.
•
Suitable metal drain pans should be installed under each water heater. The pan must be piped to an adequate drain and limit the water level to a maximum depth of 1-3/4” (4.4 cm) and be two inches (5 cm) wider than the heater.
* PIPE TO ADEQUATE DRAIN ** OPTIONAL FOR HEATER ISOLATION
